MACHINE lORMAKING CROSS-TIE LINKS.

Specification of Letters Patent.

To all wlw/m. it may concern:

Be it known that I, GARY B. SMITH, a

`citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented. a new and useful Machinefor Making Cross-Tie Links, of which the vfollowing is a specilication.

The device :forming the subject-matter of this application is a machine adapted to be employed for the making of cross ties of the sort commonly used iii the .manufacture oit' spring beds, although, obviously the ma chine may `be y put to other uses.

Une object of the present inventiongis to provide novel. means for putting the initial bend into a length of wire.

Another object of the invention is to provide novel means for ciiitting the section of wire into a predetermined length, and for turning both the bend and the ends ot' the severed section to form hoolrs at the lends oft' the cross tie.`

Another object of the invention is to provide novel means for feeding the length of Wire intermittently for shaping.

The invention aims to provide novel means for removing the finished product from the machine.

` It is within the scope of the invention to provide novel driving mechanism whereby the several portions of the structure may be actuated.

`ll7ith the foregoing and other objects in view lwhich will appear as the description proceeds, the invention resides in the coinbination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment oil the invention herein disclosed can bemade within the scope ofwhat is claimed without departing from the spirit olf the invention.

In the draWings-Figure 1 shows the ini vention in side elevation; Fig. Q. is a top plan; Fig. 3 is a longitudinal section on the line 3-3 of Fig.`2; Fig. l1 is an elevation showing the `opposite side ot' the structure :from that depicted in Fig. 1; Fig. 5 is a transverse section on the line 5-5 of Fig. Q.; Figj is a transversesectioii on the line G-Gof Fig. 2; 7 is a horizontal section on the line 7-7 of Fig. 6; Fig. 8 is a horizontal section on the line 8-8 of Fig. 6; Fig. 9 is a sectional side elevation on the line 9-9 of 7; Fig."10 is a section on the line 10-10 of Fig. 8.; Fig. 11 is a plan showing a slightniodiiicatioii; Fig. 12 is an Patented Nov. 10, 1914. Application filed March 18, 1913. Serial No. 755,100.

perspective of considered the forward end, that end to which the reference character B is applied being` considered the rear endde soriptive terms being selected accordingly. ln cari-yin out the invention there is provided a supportingstructure, comprisingam base 1 and a superposed cap Q. The base l adjacent the forward end of the supporting structure is provided with longitudinally extended guides 3 and at the `orwardfends of which are located standards l1 supporting a shaft 5 upon which is mounted to swing in a vertical plane, a trip 6. A spring 7 shown in Fig. f2, is connected with one of the standards L1 and with the trip 6, the spring 7 servn ing to swing the trip G forwardly and downwardly, into engagement with a shaft 8 `which is journaled in the standards 4L. Proliecting iliorwardly from the shaft 8 is aguidc At one end, the shaft 8 is equipped with a crank arm 10, pivotally connected with an actuating' member 11 which may be aslide,

the actuating member being held inplace upon the base 1 for longitudinal movement by the means of a guide 12 and by means of a screw 141, the screw 1d entering the base 1 .y and being slidably received in an elongated slotl in the actuating niemberll.

Mounted to reciprocate between the guides 3 is a cross head 16 to which is secured a cap 17, shown most clearly in Fig. 3. At its` ends, the cap 17 is equipped with upstanding ears 18 having alined openings 19. An angular grip 20 is p1votally`supported uponthe cross head 16 as indicated at 20".

The grip 20 comprises a forwardly extended .l

shank 9.1 and a depending jaw 22, the lower end. o'l which may be serrated. The lower end of the jaw 22 lies between the ears 18. 110

Nuts 23 .are threaded upon the shank `2101 the grip 20.

The wire to be fashioned into cross ties is denoted by the numeral 24. The wire 24 extends through the openings 19 in the ears 18 which are connected with the cross head.

lVhen the actuating member 11 is thrustrearwardly, the crank arm 10 will be actuated, rotating the shaft 8 and causing a depression of the free, forward end of the guide 9. The upper end of the trip G is then "exposed, and rests upon the shaft S. Suppose that the cross head 16 is thrust for Wardly. Then the nuts 23 on the shank 21 of the grip 20 will ride along, engage and tilt the trip G and thus force the lower end of the aw 22 into engagement with the wire 24, the wire 24 being bound against the cap 17. lf now the cross head 16 be moved rearwardly, the wire 24 will be moved rearwardly, the trip tilting to permit nuts 23 to move free from the end of the trip. So long as the cross-head 16 is moving rearwardly, and so long as the wire 24 is under tension, the lower end of the jaw will be maintained in binding relation to the wire. But, however, when the rearward movement of the cross head 1G ceases, the jaw 22 will no longer engage the wire 24 and the cross head 16 may move forwardly without carrying the wire 24 with it. In this manner, the wire 24 will be moved rearwardly with a step-by-step movement.

At times it may be desirable to permit the cross head 16 to reciprocate freely without moving the wire 24 rearwardly. Under '351 such circumstances, the guide 9 is raised through thermedium of the actuating meinber 11, the crank arm 10 and the shaft 8 until the upper edge of the guide 9 is in 'substantial alinement with the upper, forward end of the trip G. Then, the nuts 23 will not engage with the forward end of the trip 6, and since the trip 6 will not be rocked in a rearward direction, the shank 21 of the grip 20 will not be elevated, and the jaw 22 will not be forced downwardly into engagement with the wire 24.

Passing now to a description of the means whereby a reciprocatory movement is imparted to the cross head 16, it will be noted that the cross head is provided with a screw bolt 25 upon which is pivoted the forward end of a link 26, the rear end of which is pivoted to a crank arm 27 secured to one end of drive shaft 28 journaled between the base 1 and the cap 2, as clearly shown in Fig. 3. Attached to the opposite end of the drive shaft 28 is a sprocket wheel 29 or other driving element whereby the shaft 28 may be rotated from a prime mover. The shaft 28 carries a sprocket wheel 30 about which is trained a sprocketchain 31. This sprocket chain 31 extends forwardly and is adapted to actuate a mechanism (not shown) whereby the wire 24 is fed to the cross head 16.

An upright shaft 32 is mounted in the cap 2, the upper end of the shaft 32 being curved as indicated at 33, the end 33 of the shaft being engaged in the cap 2, so that the shaft 32 cannot rotate. Journaled upon the shaft 32 and located in a recess in the cap 2 is a bending member 34. Comparing Figs. 6 and 7, it will be seen that the member 34 is provided with a transverse slot 35, the inner edges of which are indicated by the reference characters 36 and 37. These edges 36 and 37 are not in alinement. The slot in the bending member 34 is disposed opposite to a horizontally positioned, longitudinally extended slot 3Sv in the side of the cap 2. Located in front of the slot is an eye 39 through which the wire 34 passes before the wire enters the slot 38.

The mouth of the slot 38 is closed `by a i cover plate 40 held in place by securing elements 41, the securing elements 41 being received in slots 41a (see Fig. 10) formed transversely in the cover plate. The `cover plate is thus permitted to have a vertical movement so that it may open and close the slot 3S. Projecting from the cover plate 40 are lugs 42 received in inclined notches 43 formed in an actuating bar 44, upheld for sliding movement by the securing elements 41 and received in a slot 45 formed in a lug 46 which outstands from the side ofthe cap 2. The lugs 42 and the notches 43` constitute interengaging elements coacting to move the cover plate or closure 40 to and from the slotor opening 38. A. pin 47 (see Fig. 8) extends across the slot 45 and guides the bar 44 in its reciprocating movement. The bending member 34 is provided with anup` right pin 49 which is received in a notch 48 formed in the inner edge of the actuating bar 44. The pin 49 constitutes an eccentric element on the bending member 34, which element coperates with the actuating `bar 44. The bending member 34 extends into a pinion 50 and is held for rotation therewith by a cap 51, the cap being secured in place by a tubular bolt 52 which enters the upper end of the bending member 34, as will be understood best from Fig. 3.

Letl it be supposed that the wire 24, in a straight length, has been moved by the cross head 16` in a rearward direction until the wire has passed? through the slot 35fin the bending member 34 and into the slot 38 in the cap 2. If'the bending member 34 be r0l tated through the medium of the pinion 5,0, the wire 34 will be bentV as indicated at 53 in Figs. 7 and 13, around the shaft 32. Then the bending member 34 is rotated, the same through the medium of the pin 49 will impart a sliding movement to the bar 44.

The inclined notches 43 in the bar 44 engage the lugs 42 on the coverplate 40 and effect an elevation ofthe fcover plate, so that'the Thus, when the Wire 34: isbent as indicated at 53, the free end of theivire Will be permitted to swing forwardly and out of the slot 38. After the Wire has been bent, as indicated at 53, the bar 14E will be drawn rearwardly by the pin 49 and thus the cover plate 40 will be permitted to move downwardly, covering the slot 38, so that the cover plate will actas a guide for the rear, free curved end of the Wire, when the Wire is moved rearwardly. the `operation above described, the bend Willbeplaced in the Wire `as indicated at 53. The bending member 3l rotates first in one direction yand then in an opposite direction, and this motion is imparted to the bending member through the medium of a bar 54 which is supported for sliding movement on top of the cap 9.. `The bar 54 is provided with a rack 55 Which meshes into the pinion 50, one end of the bar :5f-l being slidably received beneath a guide 5G, attached to the cap 2, therebeing ascrew 57 which enters ythe cap and is receivedin an elongated slot `naled in the cap 2. `mutilated pinion 62 meshing into a inuti- 58 in the bar 54, the slot 58 being shown most clearly in Fig. 2. One end of a link 59 is pivoted to the rack bar 54, the other `end of the link being pivoted to a crank disk 60 secured to a shaft G1 which is jour- The shaft `G1 carries a l ated pinion 63 secured to the driveshaft 28.

From the foregoing it will be seen that a reciprocating ino-vement Will bel imparted `to the bending member 34 through a gear train comprising the rack bar 54u55, the link 59, the crank disk 60, the shaft G1, the pinion 62 and G3, the shaft 28 and the driving member or sprocket Wheel Q9` It has been stated hereinbefore that the p end 33 of the shaft 32 is engaged in the cap 2. Owing to this fact, the shaft 32 is pre` vented from rotating, andwhen the bend is formed around the shaft 32 by the action of the edge or shoulder 37, the Wire will not p be advanced when the bend 53 is made. This operationsecures an even and equal length i. in the free ends which are `formed by the bends indicated at i i Journaled in the supporting structure is a shaft 89 terminally provided with a head 65, the end of which is providedwwith an` outstandingshoulder 66, one end of WhichA defines a cutting edge 67 adapted to cojoperate with an anvil 68 held in the cap 2.`

The head is equipped with afprong 69 Which overhangs the shoulder 66. .The end face ofthe head 65 and the adjacent edge of ,the prong69, converge toward the cutting edge 67, as shown at 70. Attached to the prong 69 is an offset stop 71. Mounted for `iongitudinal sliding movement Within the.y

shaft 89 is a tubular ejector 64 and locatedy Within the ejector 64 is asupporting rod 72.l The loop "or bend 53 in the Wire isadvanced` across the shoulder 66 by the action of the cross head 16, and when the shaft 89 andthe head 65 are rotated,` the cutting edge 67 of the shoulder 66 will coperate With the anvil 68 and cut off the wire at the point indicated' at 74 in Fig. le. The shoulder 66 will then move up around the supporting rod 72, the ends of the U-shaped piece of Wire shown in Fig. 14 being formed into a pair of hooks shown at T5 in Fig. 15. The arms of the itl-shaped piece of wire indicated in Fig. 14 are engaged between the converging faces 7 Q.. of the prong 69 and the shoulder 66, and are brought into converging relation as shown at 73 in Fig. 16.

1While the cutting and bending operation above referred to is taking place, the U- shaped section of wire is upheld by a snpport 76.

A block 'TT .is attached to the base 1 by ineansof screws 78, or is held thereon in any other desired manner. Through the block T7 passes `the supporting rod 72 and the same .is held in place by a set screvv 79. The ejector G4 is mounted in a head 80 and is `held therein by a set screw 81.

In order to impart a reciprocating movement-of the ejector' 64,11 lever 82 is pivotally connected with the head 80, as indicated at 84, the level" being fulcrumed intermediate its ends as shown at83, upon a projecting portion of the base 1. At its forward end, the lever 82 is equipped with a depending finger 85 which registers in a cam groove 86 formed in a disk 87 secured to the drive shaft 28. j j

Secured to the shaft 89 `is `a pinion 88 meshing into a rack 90 formed` upon the lower rear portion of the bar 54. Another tubular shaft 91 (see Fig. 7) and resembling the shaft 89, is journaled for rotation in the cap Q. The shaft 91 1s equipped with a. pinion 92 which meshes into the pinion 88. Secured to the shaft 91 is a head 93 provided with an outstanding shoul-` der 94, in which a pin 95 is slidably mounted, the pin 95 being constrainedbya spring 9G to project beyond the shoulder. Located `Within the shaft 9lis a tubular ejector 97 by means of a set screw 98 in the head 80. A guidev99 is located Withinthe ejector 97 and bymeans of a. set screw 100, the guide 99 is held in the block 77. The guide 99 projects beyond the head 93 and is curved as indicated at 101. The bend of the partially finished product `shown in Fig. 15 is received by the shoulder 94 and is caught by the pin 95. l/Vhen the head 93 is rotated, the piirivill turn over the bend 53, across the guide 99, to form a hook indicated at 10Q.

A rotatory, oscillating motion is imparted to the head 65 by a" gear train comprising the shaft'QS, the pinion 63, the Npinion 62',

lthe shaft 61,the crank disk 60, the link-59,-

therack90l and the pinion 88. From the Ypinion 88 motion is transmitted to the pinion 92 and thence into the shaft 91 and the `head 93. `VVhenfthe 'shaft 28 is rotated, the disk 87 is rotated and the cam groove 86 .through the medium of the finger 85 will tilt the lever 82, the lever-.82 actuating the head 80 and the head l80 sliding the ejectors 84 land 97 on the guides 72 and 99 respectively.

The ejector 64 will push the hooks 75 off the end of the rod 7 2and the ejector 97 will advance the hook 102 along the guide 99. The stop 71 serves to prevent the finished cross .tie` from swinging around too far in a horizontal direction when the hooks 75 are crowded by the ejector 64 ofil the end of the rod .72. The cross ties by theabove operation will be deposited one by one in depending positions .upon the guide 99 and as one cross tieafter another is deposited upon the guide,the ycross ties will be moved along onto the curved end 101 of thel guide, from which position they may be readily hooked onto the chains of links of the bed fabric.

It is desirable that the bend 53 be not made in the wire until the advanced portion of the wire be cut off as indicated at 74. In

the invention isshown, the modification concap- 107.

sisting in equipping the guide 99 with a head 106 comprising a body 103, and a curved end 104, the body land the end 104 having ay slot 105 across which extends a versely and the end 104 lies at an angle thereto. The hook 102,-53 rides into they slot 105 and the tie is advanced alongvthe head. Owing to the fact that the body is i transversely inclined as clearly shown in Fig. 18, that end of the tie which carried thejhooks 75 is depressed as the tie moves along the head. As a consequence, when the tie is advanced along the head, that end of the tie which carries the hooks 75 is permitted tov pass under one chain of links inv the fabric. The hook 102-53 as it traverses the end 104, is engaged with this chain and the hooks 75 are engaged with another parallel chain, it being noted that after the tie [passes off the transversely inclinedlbody 103 andtraverses the end 104, the tie is moved to ,a positionv parallel to the plane defined by the two chains above referred to.

i Especial attentionis directed to the curved:

form ofl thevv crank v 27. The form Q. the -eranks important, smce., owing to its curved The body'. 103 is inclined trans-` bend 53 is made, is permitted to swing through the crank.

Obviously by loosening the bolt 52, the pinion may be rotated upon the bending member 34. In this maimer, the edge 37 may be adjusted, so as to exercise itsfunction as hereinbefore set forth. j

The ,operation of the structurehas been dealt with hereinbefore stepk-b -step, butl generally considered, is as 'fo lows :-The shaft 28 through the medium of the crank 27 and the link 26 causes areciprocation of the cross head 16, the trip 6 causin the grip 20 to engage the Wire 24 and sli e the same. The bend indicated at 53 is formed around the shaft 32 by the edge 37 of the bending member 34, the bending member 34 being rotated by means of the rack 55 on the bar 54, the bar 54 being actuated by the link 59, the cam disk the shaft 61, the pinion 62, thevpinion 63 and the` shaft 28. Thecut indicated at 74 in the finished product and the bend indicated at 75 'are formed by the shoulder 66, the head 65 and the shaft 89 being rotated through the medium of the pin- .p

ion 88 and the rack 90 on the rackba-r 54. The bend indicated at 102 in the finished product is secured by .the shoulder 94, the head 93 being rotated by the shaft 91, which in its turn is `rotated by the intermeshing pinions 89 and'92.V The ejectors 97 and 64 are operated from the head by meansof the lever 82, the lever being actuated from the shaft 28 by the disk 87 and its groove 86. Owing tothe fact that the mutilated pinion 63 meshes into pinion 62 for a ortion only of the time during which the shaft 28 is rotating,- there will be a pause between each completeforward and backward stroke of the rackbar 54, and consequentlyr between each movement of theheads 65, and 93, such movement comprising a rotation'first in one direction and then in the other. Owing to the fact that the mutilated pinion 63 does not mesh continuously into the pinion 62,'

the reciprocating movement of the cross head 16 and consequently the advance of the wire 24 will be properly timed with respect to the cutting and bending operations.
